Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Scalloped Fish or Oysters
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Butter some scallop shells or ramekin cases and sprinkle a layer of breadcrumbs in each.
Make the sauce
In a saucepan, melt the butter over medium heat.
Stir in the flour and cook for a minute.
Gradually add the milk or fish stock, stirring until it boils.
Place a tablespoon of the sauce into each shell.
Assemble and bake
Add the cooked fish on top, season with salt and pepper, and cover with more breadcrumbs.
Bake in the oven for 20-25 minutes until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked fish
- Provides the main filling and body of the dish.
- Butter
- Enriches the sauce and helps the breadcrumbs brown in the oven.
- Flour
- Thickens the milk or stock into a smooth sauce.
- Milk or fish stock
- Forms the liquid base of the sauce, adding moisture and richness.
The step that matters
Cooking the flour into the butter and bringing the sauce to a boil. Cooking the flour briefly in the butter removes its raw taste, and the sauce must boil after the liquid is added so the starch thickens fully. Adding liquid gradually while stirring prevents lumps from forming.
